FIG. 4 is a view of utilizing a remote control device according to an embodiment of the present invention.
FIG. 4A illustrates that a pointer 205 corresponding to the remote control device 200 is displayed on the display unit 180.
A user can move or rotate the remote control device 200 vertically or horizontally. The pointer 205 displayed on the display unit 180 of the display device 100 corresponds to a movement of the remote control device 200. Since the corresponding pointer 205 is moved and displayed according to a movement on a 3D space as show in the drawing, the remote control device 200 can be referred to as a spatial remote controller.
FIG. 4B illustrates that if a user moves the remote control device 200, the pointer 205 displayed on the display unit 180 of the display device 100 is moved to the left in correspondence thereto.
Information on a movement of the remote control device 200 detected through a sensor of the remote control device 200 is transmitted to the display device 100. The display device 100 can calculate the coordinates of the pointer 205 from the information on the movement of the remote control device 200.

FIG. 4C illustrates that while a specific button in the remote control device 200 is pressed, a user moves the remote control device 200 away from the display unit 180. Thus, a selection area in the display unit 180 corresponding to the pointer 205 can be zoomed in and displayed largely.
On the other hand, if a user moves the remote control device 200 close to the display unit 180, a selection area in the display unit 180 corresponding to the pointer 205 can be zoomed out and displayed reduced.
On the other hand, if the remote control device 200 is away from the display unit 180, a selection area can be zoomed out and if the remote control device 200 is close to the display unit 180, a selection area can be zoomed in.
Additionally, if a specific button in the remote control device 200 is pressed, the recognition of a vertical or horizontal movement can be excluded. That is, if the remote control device 200 is moved away from or close to the display unit 180, the up, down, left, or right movement can not be recognized and only the back and forth movement can be recognized. While a specific button in the remote control device 200 is not pressed, only the pointer 205 is moved according to the up, down, left or right movement of the remote control device 200.
Moreover, the moving speed or moving direction of the pointer 205 can correspond to the moving speed or moving direction of the remote control device 200.
Furthermore, a pointer in this specification means an object displayed on the display unit 180 in correspondence to an operation of the remote control device 200. Accordingly, besides an arrow form displayed as the pointer 205 in the drawing, various forms of objects are possible. For example, the above concept includes a point, a cursor, a prompt, and a thick outline. Then, the pointer 205 can be displayed in correspondence to one point of a horizontal axis and a vertical axis on the display unit 180 and also can be displayed in correspondence to a plurality of points such as a line and a surface.

Hereinafter, prior to examining various embodiments implemented through the mobile terminal 500, the above-listed components are described in more detail with reference to FIG. 5.
First, in describing the wireless communication unit 510, the broadcast receiving module 510 of the wireless communication unit 511 can receive a broadcast signal and/or broadcast related information from an external broadcast management server through a broadcast channel. The broadcast channel can include a satellite channel and a terrestrial channel. At least two broadcast receiving modules for simultaneous broadcast reception for at least two broadcast channels or broadcast channel switching can be provided to the mobile terminal 100.
The mobile communication module 512 can transmit/receive a wireless signal to/from at least one of a base station, an external terminal, and a server on a mobile communication network established according to the technical standards or communication methods for mobile communication (for example, Global System for Mobile communication (GSM), Code Division Multi Access (CDMA), Code Division Multi Access 2000 (CDMA2000), Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EV-DO), Wideband CDMA (WCDMA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Long Term Evolution (LTE), or Long Term Evolution-Advanced (LTE-A)).
The wireless signal can include various types of data according to a voice call signal, a video call signal, or text/multimedia message transmission.
The wireless internet module 513 refers to a module for wireless internet access and can be built in or external to the mobile terminal 500. The wireless internet module 513 can be configured to transmit/receive a wireless signal in a communication network according to wireless internet technologies.
The wireless internet technology can include Wireless LAN (WLAN), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), World Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Long Term Evolution (LTE), and Long Term Evolution-Advanced (LTE-A) and the wireless internet module 513 transmits/receives data according at least one wireless internet technology including internet technology not listed above.
From the viewpoint that wireless internet access by WiBro, HSDPA, HSUPA, GSM, CDMA, WCDMA, LTE, and LTE-A is achieved through a mobile communication network, the wireless internet module 513 performing wireless internet access through the mobile communication network can be understood as one type of the mobile communication module 512.
The short-range communication module 514 can support short-range communication by using at least one of Bluetooth™, Bluetooth Low Energy (BLE), Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, Near Field Communication (NFC), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, or Wireless Universal Serial Bus (USB) technologies. The short-range communication module 514 can support wireless communication between the mobile terminal 500 and a wireless communication system, between the mobile terminal 500 and another mobile terminal 500, or between networks including the mobile terminal 500 and another mobile terminal 100 (or an external server) through wireless area networks. The wireless area networks can be wireless personal area networks.
Here, the other mobile terminal 500 can be a wearable device (for example, a smart watch, a smart glass, and an HMD) that is capable of exchanging data (or interworking) with the mobile terminal 500. The short-range communication module 514 can detect (or recognize) a wearable device around the mobile terminal 500, which is capable of communicating with the mobile terminal 500 Furthermore, if the detected wearable device is a device authenticated to communicate with the mobile terminal 500, the control unit 580 can transmit at least part of data processed in the mobile terminal 500 to the wearable device through the short-range communication module 514. Accordingly, a user of the wearable device can use the data processed in the mobile terminal 500 through the wearable device. For example, according thereto, if a call is received by the mobile terminal 500, a user can perform a phone call through the wearable device or if a message is received by the mobile terminal 500, a user can check the received message.
The location information module 515 is a module for obtaining the location (or the current location) of a mobile terminal and its representative examples include a global positioning system (GPS) module or a Wi-Fi module. For example, the mobile terminal can obtain its position by using a signal transmitted from a GPS satellite through the GPS module. As another example, the mobile terminal can obtain its position on the basis of information of a wireless access point (AP) transmitting/receiving a wireless signal to/from the Wi-Fi module, through the Wi-Fi module. If necessary, the position information module 115 can perform a function of another module in the wireless communication unit 510 in order to obtain data on the location of the mobile terminal substitutionally or additionally. The location information module 115 is a module for obtaining the position (or the current position) of the mobile terminal and is not limited to a module directly calculating and obtaining the position of the mobile terminal.
Then, the input unit 520 is used for inputting image information (or signal), audio information (or signal), data, or information inputted from a user and the mobile terminal 500 can include at least one camera 521 in order for inputting image information. The camera 521 processes image frames such as a still image or a video obtained by an image sensor in a video call mode or a capturing mode. The processed image frame can be displayed on the display unit 551 or stored in the memory 570. Moreover, a plurality of cameras 521 equipped in the mobile terminal 500 can be arranged in a matrix structure and through the camera 521 having such a matrix structure, a plurality of image information having various angles or focuses can be inputted to the input terminal 500. Additionally, the plurality of cameras 521 can be arranged in a stereo structure to obtain the left and right images for implementing a three-dimensional image.
The microphone 522 processes external sound signals as electrical voice data. The processed voice data can be utilized variously according to a function (or an application program being executed) being performed in the mobile terminal 500. Moreover, various noise canceling algorithms for removing noise occurring during the reception of external sound signals can be implemented in the microphone 522.
The user input unit 523 is to receive information from a user and if information is inputted through the user input unit 523, the control unit 580 can control an operation of the mobile terminal 500 to correspond to the inputted information. The user input unit 523 can include a mechanical input means (or a mechanical key, for example, a button, a dome switch, a jog wheel, and a jog switch at the front, back or side of the mobile terminal 500) and a touch type input means. As one example, a touch type input means can include a virtual key, a soft key, or a visual key, which is displayed on a touch screen through software processing or can include a touch key disposed at a portion other than the touch screen. Moreover, the virtual key or visual key can have various forms and can be disposed on a touch screen and for example, can include graphic, text, icon, video, or a combination thereof.
Moreover, the sensing unit 540 can sense at least one of information in a mobile terminal, environmental information around a mobile terminal, or user information and can then generate a sensing signal corresponding thereto. On the basis of such a sensing signal, the control unit 580 can control the drive or control of the mobile terminal 500 or can perform data processing, functions, or operations relating to an application program installed in the mobile terminal 500. Representative sensors among various sensors included in the sensing unit 540 will be described in more detail.
First, the proximity sensor 541 refers to a sensor detecting whether there is an object approaching a predetermined detection surface or whether there is an object around by using the strength of an electromagnetic field or infrared, without mechanical contact. The proximity sensor 541 can disposed in an inner area of a mobile terminal surrounded by the touch screen or around the touch screen.
Examples of the proximity sensor 541 can include a transmission-type photoelectric sensor, a direct reflective-type photoelectric sensor, a mirror reflective-type photoelectric sensor, a high-frequency oscillation-type proximity sensor, a capacitive-type proximity sensors, a magnetic-type proximity sensor, and an infrared proximity sensor. If the touch screen is a capacitive type, the proximity sensor 541 can be configured to detect the proximity of an object by changes in an electric field according to the proximity of the object having conductivity. In this case, the touch screen (or a touch sensor) itself can be classified as a proximity sensor.
Moreover, for convenience of description, an action for recognizing the position of an object on the touch screen as the object is close to the touch screen without contacting the touch screen is called “proximity touch” and an action that the object actually contacts the touch screen is called “contact touch”. A position that an object is proximity-touched on the touch screen is a position that the object vertically corresponds to the touch screen if the object is proximity-touched. The proximity sensor 541 can detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). Moreover, the control unit 580 processes data (for information) corresponding to a proximity touch operation and a proximity touch pattern, detected through the proximity sensor 541, and furthermore, can output visual information corresponding to the processed data on the touch screen. Furthermore, according to whether a touch for the same point on the touch screen is a proximity touch or a contact touch, the control unit 580 can control the mobile terminal 500 to process different operations or data (or information).
The touch sensor detects a touch (or a touch input) applied to the touch screen (or the display unit 551) by using at least one of various touch methods, for example, a resistive film method, a capacitive method, an infrared method, an ultrasonic method, or a magnetic field method.
For example, the touch sensor can be configured to convert a pressure applied to a specific portion of the touch screen or changes in capacitance occurring at a specific portion into electrical input signals. The touch sensor can be configured to detect a position and area that a touch target applying a touch on the touch screen touches the touch sensor, a pressured if touched, and a capacitance if touched. Here, the touch target, as an object applying a touch on the touch sensor, can be a finger, a touch pen, a stylus pen, or a pointer, for example.
In such a manner, if there is a touch input on the touch sensor, signal(s) corresponding thereto are sent to a touch controller. The touch controller processes the signal(s) and then transmits corresponding data to the control unit 580. Therefore, the control unit 580 can recognize which area of the display unit 551 is touched. Herein, the touch controller can be an additional component separated from the control unit 580 or can be the control unit 580 itself.
Moreover, the control unit 580 can perform different controls or the same control according to types of a touch target touching the touch screen (or a touch key equipped separated from the touch screen). Whether to perform different controls or the same control according to types of a touch target can be determined according to a current operation state of the mobile terminal 500 or an application program in execution.
Moreover, the above-mentioned touch sensor and proximity sensor are provided separately or combined and can thus sense various types of touches, for example, short (or tap) touch), long touch, multi touch, drag touch, flick touch, pinch-in touch, pinch-out touch, swipe touch, and hovering touch for the touch screen.
The ultrasonic sensor can recognize position information of a detection target by using ultrasonic waves. Moreover, the control unit 580 can calculate the position of a wave source through information detected by an optical sensor and a plurality of ultrasonic sensors. The position of the wave source can be calculated by using the property that light is much faster than ultrasonic wave, that is, a time that light reaches an optical signal is much shorter than a time that ultrasonic wave reaches an ultrasonic sensor. In more detail, the position of the wave source can be calculated by using a time difference with a time that ultrasonic wave reaches by using light as a reference signal.
Moreover, the camera 520 described as a configuration of the input unit 521 can include at least one of a camera sensor (for example, CCD and CMOS), a photo sensor (or an image sensor), or a laser sensor.
The camera 521 and the laser sensor can be combined to detect a touch of a detection target for a three-dimensional image. The photo sensor can be stacked on a display device and is configured to scan a movement of a detection target close to the touch screen. In more detail, the photo sensor mounts a photo diode and a transistor (TR) in a row/column and scans content disposed on the photo sensor by using an electrical signal changing according to an amount of light applied to the photo diode. That is, the photo sensor can calculate the coordinates of a detection target according to the amount of change in light and through this, can obtain the position information of the detection target.

Then, a communication system using the mobile terminal 500 is described according to an embodiment of the present invention.
First, the communication system can use different wireless interfaces and/or physical layers. For example, a wireless interface available to the communication system can include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications Systems (UMTS) (especially, Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A), and Global System for Mobile Communications (GSM)).
Hereinafter, for convenience of description, description is made limited to CDMA. However, it is apparent that the present invention is applicable to all communication systems including Orthogonal Frequency Division Multiplexing (OFDM) wireless communication systems in addition to CDMA wireless communication systems.
The CDMA wireless communication system can include at least one terminal 100, at least one base station (BS) (it can be referred to as Node B or Evolved Node B), at least one base station controllers (BSCs), and a mobile switching center (MSC). MSC can be configured to be connected to Public Switched Telephone Network (PSTN) and BSCs. BSCs can be connected being paired with a BS through a backhaul line. The backhaul line can be provided according to at least one of E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Accordingly, a plurality of BSCs can be included in a CDMA wireless communication system.
Each of a plurality of BSs can include at least one sensor and each sensor can include an omni-directional antenna or an antenna indicating a specific radial direction from a BS. Additionally, each sensor can include at least two antennas in various forms. Each BS can be configured to support a plurality of frequency allocations and each of the plurality of frequency allocations can have a specific spectrum (for example, 1.25 MHz, 5 MHz, and so on).
The intersection of a sector and a frequency allocation can be referred to as a CDMA channel. A BS can be referred to as a Base Station Transceiver Subsystem (BTS). In such a case, one BSC and at least one BS together can be referred to as “BS”. A BS can also represent “cell site”. Additionally, each of a plurality of sectors for a specific BS can be referred to as a plurality of cell sites.
A Broadcasting Transmitter (BT) transmits broadcast signals to the terminals 100 operating in a system. The broadcast reception module 511 shown in FIG. 5 is provided in the terminal 100 for receiving broadcast signals transmitted from the BT.
Additionally, GPS can be linked to a CDMA wireless communication system in order to check the location of the mobile terminal 500. Then, a satellite helps obtaining the location of the mobile terminal 500. Useful location information can be obtained by at least one satellite. Herein, the location of the mobile terminal 500 can be traced by using all techniques for tracing the location in addition to GPS tracking technique. Additionally, at least one GPS satellite can be responsible for satellite DMB transmission selectively or additionally.
The location information module 515 in a mobile terminal is for detecting and calculating the position of the mobile terminal and its representative example can include a GPS module and a WiFi module. If necessary, the position information module 115 can perform a function of another module in the wireless communication unit 510 in order to obtain data on the location of the mobile terminal substitutionally or additionally.
The GPS module 115 can calculate information on a distance from at least three satellites and accurate time information and then apply triangulation to the calculated information, in order to accurately calculate the 3D current location information according to latitude, longitude, and altitude. A method for calculating location and time information by using three satellites and correcting errors of the calculated location and time information by using another one satellite is being widely used. Additionally, the GPS module 115 can speed information as continuously calculating the current location in real time. However, it is difficult to accurately measure the location of a mobile terminal by using a GPS module in a shadow area of a satellite signal such as a room. Accordingly, in order to compensate for the measurement of a GPS method, a WiFi Positioning System (WPS) can be utilized.
WPS is a technique for tracking the location of the mobile terminal 500 by using a WiFi module in the mobile terminal 500 and a wireless Access Point (AP) for transmitting or receiving wireless signals to or from the WiFi module and can mean a Wireless Local Area Network (WLAN) based location measurement technique using WiFi.
A WiFi location tracking system can include a WiFi location measurement server, a mobile terminal 500, a wireless AP connected to the mobile terminal 500, and a database for storing arbitrary wireless AP information.
The mobile terminal 500 in access to a wireless AP can transmit a location information request message to a WiFi location measurement server.
The WiFi location measurement server extracts information of a wireless AP connected to the mobile terminal 500 on the basis of a location information request message (or signal) of the mobile terminal 500. Information of a wireless AP connected to the mobile terminal 500 can be transmitted to the WiFi location measurement server through the mobile terminal 500 or can be transmitted from a wireless AP to a WiFi location measurement server.
Based on the location information request message of the mobile terminal 500, the extracted information of a wireless AP can be at least one of MAC Address, Service Set Identification (SSID), Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), channel information, Privacy, Network Type, Signal Strength, or Noise Strength.
As mentioned above, the WiFi position measurement server can extract wireless AP information corresponding to a wireless AP that the mobile terminal 500 access from a pre-established database by using information of the wireless AP connected to the mobile terminal 100. At this point, information of arbitrary wireless APs stored in the database can information such as MAC Address, SSID, channel information, Privacy, Network Type, latitude and longitude coordinates of a wireless AP, a building name where a wireless AP is located, the number of floors, indoor detailed location (GPS coordinates available), the address of the owner of an AP, and phone numbers. At this point, in order to remove a mobile AP or a wireless AP provided using illegal MAC address during a measurement process, a WiFi location measurement server can extract only a predetermined number of wireless AP information in high RSSI order.
Then, the WiFi location measurement server can extract (or analyze) the location information of the mobile terminal 500 by using at least one wireless AP information extracted from the database. By comparing the included information and the received wireless AP information, location information of the mobile terminal 500 is extracted (or analyzed).
As a method of extracting (or analyzing) the location information of the motile terminal 500, a Cell-ID method, a finger-print method, a triangulation method, and a landmark method can be used.
The Cell-ID method is a method for determining the location of a wireless AP having the strongest signal intensity in neighbor wireless AP information that a mobile terminal collects as the location of the mobile terminal. Implementation is simple, no additional cost is required, and location information is obtained quickly but if the installation density of wireless APs is low, measurement precision is poor.
The finger-print method is a method for collecting signal intensity information by selecting a reference location from a service area and estimating the location through signal intensity information transmitted from a mobile terminal on the basis of the collected information. In order to use the finger-print method, there is a need to provide a database for storing propagation characteristics in advance.
The triangulation method is a method for calculating the location of a mobile terminal on the basis of a distance between coordinates of at least three wireless APs and a mobile terminal. In order to measure a distance between a mobile terminal and a wireless AP, a signal intensity converted into distance information, Time of Arrival (ToA), Time Difference of Arrival (TDoA), and Angle of Arrival (AoA) can be used.
The landmark method is a method for measuring the location of a mobile terminal by using a landmark transmitter knowing the location.
In addition to the listed methods, a variety of algorithms can be utilized as methods for extracting (or analyzing) the location information of a mobile terminal.
As the extracted location information of the mobile terminal 500 is transmitted to the mobile terminal 500 through the WiFi location measurement server, the mobile terminal 500 can obtain the location information.
As connected to at least one wireless AP, the mobile terminal 500 can obtain location information. At this point, the number of wireless APs, which are required for obtaining the location information of the mobile terminal 500, can vary according to a wireless communication environment where the mobile terminal 500 is located.
